I continue to read and re-read instruction on homebrewing to hone my skill. I am at about 30 all grain batches to date and I simply want to ensure I improve as I go. Tonight I read this from a very popular homebrew publication:
The aim of recirculation is to draw some wort off from the bottom of the grain bed and return it to the top. Once enough wort has been recirculated in this way, the wort clears up substantially. To recirculate manually, open the spigot to the mash/lauter tun slightly and slowly collect wort in a beer pitcher or similar vessel. Keep a timer running and collect wort at a rate that would fill the pitcher in about 5 minutes. Once full, gently pour the pitcher back on top of the grain bed. Repeat this until the wort looks clearer or 20 minutes have passed. Some homebrew rigs allow you to recirculate using a pump.
Once recirculation is finished, it's time to start collecting wort. To do this, slowly open the valve on your mash/lauter tun and let the wort start trickling in to the kettle. If your lauter tun is not positioned above the kettle, you can let the wort flow into a pitcher and then pour wort into the kettle. Collect the wort at a rate such that takes about 60–90 minutes to collect the entire volume. To do this, keep the dip stick in the kettle and check on it every few minutes. Write down the time you start collecting wort and the time you cross the 1-gallon mark, 2-gallon mark, 3-gallon mark, etc."
I definitely do not run off that slow to recirculate or collect wort. Should I? Will it improve the quality of my brew? Does this apply to fly sparge, batch sparge, and no sparge equally? What say you?
